Description

Fixed twin-lock point theftproof lock

The utility model relates to a kind of theftproof lock, a kind of anti-fixed twin-lock point theftproof lock of usurping of bicycle (or motorcycle) that is used for of definitely saying so.

Traditional bicycle, anti-theft lock for motorcycle all are that lockset moves with car, can only limiting wheel behind the Vehicle locking rotate, and can not prevent from that vehicle is whole to move, and lockset is also often destroyed easily and lose antitheft effect.

The purpose of this utility model is fundamentally to overcome this shortcoming of conventional lock, for users provide a kind of real safe and reliable novel anti-burglar lock.

The utility model is achieved in that whole lockset is made up of lock and lock plug-in unit two members.Lock is a metal integral, and shape is located on the flat board like the matrix body, and this flat board is the base of lock, on fixing hole is arranged, lock can be fixed and base is embedded in underground.On the base, two rectangle columns on the matrix body are called lock.There is conjuncted boxboard to link to each other between two locks and forms integral body with lock.Two lock spacings are slightly larger than the wheel width, so that wheel can be put into therebetween.

One of them lock: on its pair of sidewalls, be useful on the perforation jack that inserts the lock plug-in unit.In appearance, this jack is upper and lower two square aperture of intermediate connection, is dumbbell shaped.Last hole connects sidewall, and caliber size is complementary with the locking bar of locking in the plug-in unit, is called latch arm hole.Following hole does not connect sidewall, and caliber size is complementary with the built-in lock of locking in the plug-in unit, is called the built-in lock hole.Between upper and lower two hole passages in this lock cylinder, open a vertical duct, be called lockpin hole, to accommodate lock pin.Terminal in the built-in lock duct is fixed the ratch that can make the garden revolution flexibly by screw rod, and its diameter, tooth pitch, tooth depth all are meshed with the hole, matrix garden of built-in lock core end face, and it is over against the lock core position of locking in the plug-in unit.Below ratch, down have a vertical duct, be called the wiring hole, communicate with the horizontal cavity between base is vertical with conjuncted boxboard, interior dress wire, the drive link of leverage has been housed in the horizontal cavity under the conjuncted boxboard, the wire upper end is fixed on the ratch outer by the garden ring, and the lower end is fixed on an end of drive link by the garden ring.In the cavity of the other end of drive link below then in another lock.In the dumbbell shaped jack of lock cylinder, the front end that connects upper and lower two holes isolate wall be " " shape, it is the vertical wall bottom of hole down, makes to have the inclined-plane of outwards dehiscing, and the dead bolt in order to built-in lock in the compression lock plug-in unit is called and presses the tongue inclined-plane.

Another lock: on the sidewall relative with last lock, have a square aperture, be called latch arm hole, its caliber size not only latch arm hole with last lock is identical, and the position is also corresponding, and this hole does not connect the lock sidewall.Have a vertical vestibule in the lock cylinder, upward logical latch arm hole, the horizontal cavity between following communications and liaison body boxboard and base.Vertically install fixedly tongue bar tube in the vestibule, the tongue bar of belt tension spring is housed in the tongue bar tube, its head is to have the dead bolt of splitting the shape inclined-plane, and its bottom connects the other end of drive link by the garden ring.Uphold and compression by spring, the tongue bar can move up and down in tongue bar tube.No external force is done the time spent, and spring is in stretched condition, the tongue bar is risen dead bolt is pushed in the latch arm hole.Two locks are being linked to be between whole conjuncted boxboard and base in the cavity, drive link is housed, and the center of bar is a balance pivot, and an end of bar is by the tongue bar bottom in garden ring connection one lock, and the other end of bar then connects the wire that links to each other with ratch in another lock by the garden ring.The length of wire and tongue bar, when making the dead bolt of tongue club head normally stretch into latch arm hole, drive link is in level and wire tension, guarantees fully dead bolt to be pulled out from latch arm hole rotating ratch 90 when spending.

Lock plug-in unit of the present utility model is an integral body that is made of built-in lock and locking bar.Built-in lock is formed by the built-in lock principle transformation of the way by general drawer-lock, and it includes built-in lock body, built-in lock core, and dead bolt three parts constitute.Built-in lock body squarely also forms one with locking bar, and built-in lock core lengthening is rectangle, and its end face is hole, an inner toothed spill garden.After will locking plug-in unit and pushing the lock jack, the hole, matrix garden of built-in lock core end face can freely enter or recess ratch along with the advance and retreat of lengthening lock core, and they can mesh fully.An inclined-plane is made in the dead bolt side of built-in lock, under normal state, dead bolt is in the state of stretching out, and it can be withdrawn in the lock body and lock core does not rotate under external force pressure, when dead bolt when returning to normal, have enough strength that the lock pin in the lock is pushed in the glossal canal in the locking bar.Key is inserted in the built-in lock, clockwise rotate 90 degree, lock core rotates dead bolt is withdrawn in the built-in lock fully.

Locking bar is a microscler square metallic object, thereunder has position, two places to have glossal canal, and one of them glossal canal correspondence the latch bolt position with the built-in lock at the conjuncted position of locking bar.The spacing of two glossal canals equals lock pin in the lock in the lock to the distance between other the lock inner tongue rod upper lock tongue.With the below, end of the locking bar at the non-conjuncted position of built-in lock, make the dead bolt of an inclined-plane in order to compressing tongue club head, make it withdraw from glossal canal and get back in the tongue bar tube.

The utility model moves by inner link gear with a key, locking or open two the lock points, its inner link gear includes: insert the built-in lock core that has dead bolt in the lock built-in lock hole, the ratch that in lock, is meshed with built-in lock core matrix garden pore area increment face, the wire that is connected with garden ring on the ratch outer, the drive link in the cavity between conjuncted boxboard and base that links to each other with the wire bottom, the tongue bar that is positioned at another lock cylinder that links to each other of the drive link other end therewith, be set with tension spring on this tongue bar, head forms dead bolt.

When a key inserts in the keyhole of built-in lock, in the direction of the clock with lock core rotation 90 degree, in the dead bolt withdrawal lock on the lock core, then the lock pin in the lock withdraws from from glossal canal in the lockpin hole that falls back owing to conduct oneself with dignity, and first lock point is unlocked.Because lock core rotates by its end face garden shape perforation and drives the ratch rotation, make the garden ring under the ratch outer be raised to the extreme higher position by extreme lower position, upwards spur the wire that is attached thereto, making drive link one end that is connected with wire is axially to go up to move with the fulcrum, and the other end that is directed at drive link moves down and pulled down tongue bar, compresses its upper spring, the dead bolt of tongue club head is withdrawed from from another glossal canal, second lock point also is unlocked, pull out the lock plug-in unit after, lock is promptly opened fully.

Essential characteristic of the present utility model is: lock by about two locks, conjuncted boxboard between two locks and base constitute an integral body, and fix on the ground, the lock plug-in unit constitutes one by locking bar and built-in lock, latch arm hole on two locks is complementary with the locking bar of locking on the plug-in unit, and the built-in lock hole on the lock then is complementary with the built-in lock of locking plug-in unit.

Advantage of the present utility model is: the mode that a confrontational lockset moves with car, lock is fixed on a bit, and guarantee when not opening lock, can not move car.As moving by force, difficulty than traditional locks is bigger, need lock is extracted with root from fixed point, perhaps that locking bar is sawed-off, owing to adopted twin-lock point method, and the distance between the lock is only bigger than wheel width, thereby must cut two otch ability moving vehicles that section is smooth in the place of being close to lock respectively.No matter the former or latter's workload are all very big, and can send sound and startle other people, the thief is hung back.If the destruction lock core, because of the hole, matrix garden of lock core and ratch also with impaired, make link gear malfunctioning and can not play a role.Because the expansion force of tension spring, the dead bolt on the tongue bar remains the state that stretches into glossal canal, can't open another lock point, thereby guarantees the safety of vehicle.
